UNI EDSTATES To all wkomtt may concern:

Be it known that I, FRANK A. BARNEY, a citizen of the United States, residing at Saginaw, llIichigan, have invented certain new and useful Improvements .in Dish; Washing Machines, of which the followlng is a specification.

This invention relates to improvements indish washing machines. I

The main object of this invention is to provide an improved dish-washingjmachine which is eflicient andone which is at the same time simple in structure and easy and convenient to operate.

' Further objects, and objects relating to structural details, will definitely appear from the detailed description to follow.

I accomplish the objects of my invention by the devices and means described in the following specification.

The .invention is clearly defined and pointed out in the claims.

ters refer to similar parts throughout the several views, and the sectional views are taken looking in the direction of the little arrows at the ends of the section lines.

Referring to the drawing, the receptacle orpan 1 is pr ovided with a plunger well e2:- tension 2 in its bottom. The plunger well is preferably arranged at one side of the re The walls of the receptacle l are preferably cylindrical, and the lower' portion tapered downwardly at 3. The ObIIGCt-OfthlS willbe pointed out. Supported within the receptacle above the plunger well 2, is acylinder 4: having an outwardly rojecting flange 5 at its upper edge an an outwardly projecting flange 6 at its lower edge. The cylinder t is supported in a spaced relation to the bottom of the receptacle to provide a slot-like discharge opening 7 for the water ejected from'the well 2 by the plunger 8 when it is forced downward into the well. This discharge opening preferably extends entirely around the plunger as shown. The water ejected from the well by the plunger is delivered across the bottom of the receptacle and dashed against the dishes in the receptacle and against the inclined portion 3 of the wall, which deflects it upwardly and against the side and,top of the receptacle where it is dashed back upon the dishes inthe receptacle. The flange 6 serves to direct the water across the bottom of the receptacle. The partition 9 is provided. with a curved seat portion 10 for the cylinder. The band 11 embraces the front of the cylinder and 1 coacts with the partition in supporting the cylinder for vertical adjustment.

The cylinder adjusting and supporting screws 12 are carried by the 'top flange 5 of the c linder and engage suitable nuts 13 mounte on the top wall of the partition. See Figs. IV and XI. The nuts are rotatably secured to the flange 5, as shown in Fig. XI. By adjusting these screws, the size ofthe discharge opening may be re 11- lated to secure the most effective resuIts. If it is desired, to operate the plunger slowly, the discharge opening should be quite small and when operated more rapidly, it may be quite large, it being desirable that the water should be ejected with considerable force, dashing against the dishes arranged in the receptacle and also up the inclined sides of the receptacle and falling back upon plunger is raised, the water quickly returns to the well. The plunger is .made of light sheet metal and is water tight so that the water will return it to its initialor elevated position.

The guard wires 14: are arranged through the flanges of the receptacle outslde of t e supporting band 11 and extend -into the well. The bottom of the well is providedwith a supporting ring 15 for the lower ends of the wires. These guard wires prevent dishes or other articles pro ecting through the opening 7 below the cylinder in which position they would be engaged by the plunger and the articles broken or the 1 plunger rendered inoperative. The Wires being arranged through the plunger flanges in this way are effectively supported and at the same time, they do not many way interfere with the adjustment of the cylinder.

The receptacle is provided wall 16 through a gasket 17 being provided for the plunger. The cover 18 embraces substantially the whole of the receptacle in front of the plunger. See Fig. VII. This permits the articles to be washed being conveniently placed in or removed 'from the receptacle.

I preferably provide a stand consisting of suitable legs 19 with a ring-like top member 20 adapted to receive the receptacle.- See Figs.v I, II and XII.

The wateris drawn from the well 2 which has a faucet 21, there being a channel 22 in the bottom of the well leading to the faucet.

For convenience in supporting the dishes. in position for most efifective work, I provide a pluralityof springs 23 which have hooks at their ends 2 1 adapted .to be en-'', gaged with lugs--25 on the bottomandside walls of the receptacle. The dishes, knives, forks, spoons, and the like can be readilyengaged with these supportin springs and are efiectively supportedthere y and at the same time, the supports do not prevent the water reaching all parts of the articles sup: ported thereby. If desired, the basket 26 may be used, which is of convenience in removing the dishes from the receptacle. The wires of which-the basket is formed also constitute means for holding the dishes in their upright position, the wires being arranged transversely so that plates and the like supported thereby may be arranged to face the discharge orifice 7.

The plunger is provided with a hand piece 27 which may e grasped at each side of the plunger.

-To adapt the structure for operation by means of the foot I provide a treadle 28 which is pivoted at 29 to one of the legs of the stand and connected by-links 30 to the with a top the dishes. When the which the plunger extends, 7

.well as hand piece 27. By this means water can be discharged with force against the dishes.

My improved washing machine is very eiiicient and is simple and easy to operate, and is of considerable capacity, as, owing to the shape of the receptacle, a quantity of dishes may be stacked or arranged therein. Only a small quantity of water is required to effectively wash a considerable quantity of dishes, and the dishes may be effectively rinsed merely by drawing off the washing water andintroducing the rinsing water.

I have illustrated and described my improvements in detail in asimple embodiment. While I am aware that various modifications are possible without departing from my invention, I have not attempted to illustrate or describe such modifications as I believe the disclosure made-will enable those skilled in the'art to which my invention relates to embody the same as conditions may require. I desire, however,

to be understoodas claiming my improvements stecifically in theform illustrated as roadly within the scope of the 'appended claims.

Having thus described my invention, what i I claim as new and desireto secure by Let-,
